Advanced tools
Offline support for AngularJS applications.
npm install angular-offline
bower install angular-offline
module.run(function (offline, $http) {
offline.start($http);
$http.get('/test.json', {offline: true})
.then(...);
});
Puting the offline flag to true in $http config will have for effect to activate the angular cache for this request and to add offline behaviour to the request.
Start or stop debug mode. It adds a lot of additional logs to understand how offline works.
module.config(function (offlineProvider) {
offlineProvider.debug(true);
});
Start offline with the requester ($http). Usually you will call this method in .run
of your application.
module.run(function (offline, $http) {
offline.start($http);
});
Specify a cache to use to stack requests (POST, PUT, DELETE...).
module.run(function (offline, $cacheFactory) {
offline.stackCache = $cacheFactory('custom-cache');
});
If you want to build an application completely offline, you will need a cache that can be stored in the localStorage. To do that, the recommended method is to use angular-cache.
You must use maxAge to specify your TTL. If you specify deleteOnExpire to "none", the cache will be served even if your TTL is exceeded.
module.run(function ($http, CacheFactory) {
$http.get('/test.json', {
offline: true,
cache: CacheFactory.createCache('bookCache', {
deleteOnExpire: 'none',
maxAge: 60000,
storageMode: 'localStorage'
})
});
});
To get more details about this, you can read the official documentation.
module.run(function ($http, CacheFactory) {
$http.defaults.cache = CacheFactory.createCache('bookCache', {
deleteOnExpire: 'none',
maxAge: 60000,
storageMode: 'localStorage'
})
});
});
You can specify the storageMode to "localStorage" to have a persistent storage for the stack.
module.run(function ($http, CacheFactory) {
offline.stackCache = CacheFactory.createCache('offlineStack', {
storageMode: 'localStorage'
});
});
To play with the example, you can start it using the command npm run example
, then opening the console and try.
- Request GET
-> interceptor.request
-> has offline flag and is online
-> clean cache
- Other requests
-> interceptor.request
-> has offline flag and is offline
-> push request in stack
-> reject
- "online" event
-> process stack
This library require the online status feature activated, you can refer to caniuse to see exactly what browsers are supported.
